[stable/grafana] syntax error in deployment.yaml in grafana 3.5.6

[rshutt]

Describe the bug
Today, a new helm chart for grafana was release. This was in it:

charts/stable/grafana/templates/deployment.yaml

Line 78 in 9e0d2f2

"command": ["/bin/sh"],

It caused the YAML parser much chagrin. Those quotes around the key name are no bueno. The next line "args": also has the same issue. Seems like it may have been a bug in converting from JSON to YAML?

Version of Helm and Kubernetes:
v2.14.1 and EKS v1.12.6

Which chart: grafana

What happened: YAML parser fail, doesn't install, rolled back to 3.5.4 I believe from 3.5.6

What you expected to happen: Things installed

How to reproduce it (as minimally and precisely as possible): Just try to do a helm install grafana/stable -n grafana --namespace grafana and watch it go. Make sure do do the repo update and the delete --purge first.

Anything else we need to know: Not really.
